Brian Renda 17:23, 5 March 2012 (EST):to add: gal, tet on, off, copper, m-toluic acid

Jeffrey E. Barrick 12:18, 7 March 2012 (EST):There is one distinction between Lac and Ara regulation that is important. Then the regulatory protein is absent in the Lac system (for example, missing from a strain), your promoter is constitutively ON. Then the regulatory protein from the Ara system is absent, your promoter is constitutively OFF. These states will also result if a mutation happens that knocks out the regulatory protein, which can make the systems differentially robust to mutations.
